[0002] 2. 2. Description of the Related Art Various respiratory masks are known that have a flexible seal that surrounds the nose and / or mouth of a user and forms a continuous seal against the user's face. The gas consumed by the user is supplied at a positive pressure into the mask to create a sealing effect. This type of mask has high altitude breathing (aircraft), swimming, mining and fire fighting activities as well as various medical diagnostic and therapeutic applications.

[0003] The medical respirator, which is particularly indispensable for the mask, forms an effective sealing structure for a user's face to prevent leakage of supply gas. In general, good mask-face seals with conventional mask structures often cause considerable discomfort to the user. This is the most important problem, especially in medical applications where the user wears the mask continuously for hours or days. In this case, the user will not be able to tolerate wearing the mask for an extended period of time, will not achieve optimal therapeutic or diagnostic objectives or cause significant disability, and will have considerable discomfort to the user.

[0004] Several types of respiratory masks for such applications are known. The most common type of mask is designed to provide an effective seal to the user's face when the user's face abuts the sealing surface of the mask and is subjected to force, from the edge of the mask to the periphery. It has an elongated, uniform smooth sealing surface, i.e. a profile with a predetermined or fixed sealing surface.
The sealing surface generally consists of a cushion filled with air or fluid or simply cast or molded with a resilient sealing member made of an elastic material such as plastic, rubber, silicone, vinyl or foam. Good.

When the outer shape of the sealing surface and the corresponding outer surface shape of the user's face are in good contact, the performance of the mask is sufficiently exhibited. For example, it is possible that the profile of the user's face coincides with the predefined profile of the sealant. However, if the sealing material has inadequate adhesion, a gap is formed at the interface between the sealing material and the face, and gas leaks from the mask through the gap. Due to the excessive force, the sealing member is compressed to close the gap, and a portion having the gap can be sufficiently sealed. Such excessive force is unacceptable as the sealant shape of the mask is forced to deform on the face and becomes high pressure elsewhere on the user's face that matches the contours of the user's face. Locations where a force exceeding the local blood pressure is applied cause considerable discomfort to the user, causing irritation and damage to the skin and sufficient pressure to stop surface blood flow. Ideally, the abutment force between the mask and the user's face should be limited, and the location where the mask seal is significantly deformed should be prevented from locally exceeding the blood pressure.

[0006] When the feed gas positive pressure is relatively high or circulates at a relatively high level, the problem of seal abutment forces above the preferred limit level becomes more pronounced. Because of the contact between the mask sealant and the user's face, the mask seals, so sufficient force must be maintained to keep the mask in contact with the face and to seal off any peak pressure leaks in the supply gas. Thus, when the supply pressure is high, conventional masks relatively tightly secure the head strap or other mask. This creates high local pressure on the face at various points along the area of the retaining strap as well as the mask seal area. Also, the user experiences discomfort even after a short period of wearing. Even where there is no point of excessive localization pressure, the tightly attached mask and head straps become very uncomfortable and the discomfort interrupts the user's treatment regimen. U.S. Pat. Nos. 2,254,854 and 2,931,356 show examples of respiratory masks having the features of a continuous cushion seal.

US Pat. No. 5,181,506 shows a protective gas mask for military use. The mask consists of three layers of facepieces, with the central layer being a thick layer of relatively hard material with V-shaped grooves. The V-shaped groove is "filled" with gel or gel and compressed air to form a bend in the face-contacting inner layer that seals the contour of the user's face. The inherent stiffness of the central layer, as well as the structural hardness of the V-shaped groove, especially when filling with gel / air, results in a relatively inflexible face seal. In practice, in order to securely attach the facepiece to the user's head, the mask is connected to a tight mounting hood to form the desired face seal. In such applications, for example, in situations where a respiratory treatment user wears a mask occasionally for an extended period of time, the above-mentioned structures with very limited comfort are not always appropriate.

[0008] In a study by SFC Stewart, V. Palmieri and GVB Cochran, several types of cushioning materials, including gels and foams, were investigated (Architectural Physics and Medical Rehabilitation, Vol. 61, 1980). May). This study compared the effect of the cushioning material used as a wheelchair cushion on skin temperature, the relative strengths and weaknesses such as heat flux and relative humidity at the skin-cushion interface. Supplying pressure above the local blood pressure level has been found to contribute to the destruction of skin tissue at the skin-cushion interface, with each of the above factors.

In the above studies, foam cushions have been shown to increase skin temperature by a few degrees after use for a few hours or so, suggesting that it is a result of the relatively low heat flux properties of the foam material. . That is, the foam material and its aerated material tend to decrease thermal conductivity. Conversely, gel pads exhibit a significantly higher heat flux than foam, and in fact are sufficient to keep skin temperature relatively constant after several hours of use. The only advantage of the foam over the gel reported in the study is that it produces a lower relative humidity than the gel at the skin-cushion interface. This is due to the open cellular tissue of the foam, which is a path of moisture dissipation. However, this superficial effect creates a problem in which the open cell foam is exposed to perspiration and promotes bacterial growth. Bacteria gradually contaminate the foam and significantly reduce the useful life of the foam.

The inherent properties of the foam mask seal irritate and damage the skin, especially the more prominent facial features such as the cheekbones and bridge of the nose.

A method for reducing the mask-face interface gap is to customize the seal to fit the size of the individual user and to match the subtle contours of the subject's face. is there. Because the purpose of customization is to align the seal with the specific external features of the user's face, i.e., the soft tissue outer surface of the subject, it can be considered as micro-customization of the seal. . For example, when a user's face has very deep wrinkles, a custom made microscopic mask closes the gaps due to wrinkles at the surface of the user interface that adheres to the deep wrinkles. in short,
The microscopic custom made seal is formed to conform to the outer surface of the subject's soft surface tissue.

Various techniques have been proposed for seals that are custom made microscopically, such as seals for facepieces, ie, face protection masks. For example, seals that are custom made microscopically, by engraving or casting a subject's face are known. A fully custom made mask is produced and a mold is formed to match the subject's face. However,
This time-consuming technique is expensive and unsuitable for conventional large-scale manufacturing processes.

[0014] The inventor has also found that, contrary to the expected results, a satisfactory sealing material cannot be obtained from a microscopic custom-made facepiece. Relatively precise microscopic custom made facepieces that exactly match the external surface of the subject's soft tissue can be used to create new gaps between the sealed structure and the subject due to changes in the sealing position and / or changes in the subject's soft tissue. Therefore, a sufficient sealing structure cannot be obtained. For this reason, since the face body of the sealing structure formed by the casting method and custom-made microscopically is designed specifically for the soft tissue of the surface shape of the subject's face when manufacturing the molded article, In general, when the contour of the subject changes or the position of the face moves, there is no function to deform the face, or the function is simply limited. For example, in a situation in which a subject moves and a face body moves, such as during sleep, a face body having a sealing structure custom-made microscopically is particularly disadvantageous.

n), whose purpose is to adapt the sealing structure to the user's general body shape, e.g. the underlying bone structure, without adapting the sealing structure to the user's detailed external shape due to external soft tissue is there. Macro customization has the advantage over microscopic customization in that gaps are less likely to form due to small changes in the subject's soft tissue or slight variations in the sealing structure. In addition, a sealing structure that is custom-made macroscopically is a more effective sealing structure than a sealing structure that is custom-made microscopically, in a situation where there are differences in the outer shapes of the bone structure and the soft tissue. For example, when protruding bone is unclear because it is covered by soft tissue, a macroscopically custom-built sealing structure matches the protruding bone structure,
Minimize the potential for leakage occurring at sites near the protruding bone.

A technique for forming the seal of a macroscopically tailored respiratory mask is to provide a wide variety of masks with a wide variety of seals. The user will use a mask with a sealing structure that optimally fits the structure of the user's face. For example, for a plurality of masks with different arched nose bridge sizes, a mask having an arched nose bridge size that best fits the user's nose can be selected. This kind of mask is
For example, there are several customization degrees that differ from a flat surface for the mask-subject interface. However, off-the-shelf masks that are made to order on a macro scale are not custom made to match the facial features of a particular user, and often have a sufficient degree of consideration for each subject in view of the particular facial contours. No custom production is performed. For example, off-the-shelf macro-custom masks generally do not provide a satisfactory seal for subjects with unique facial features, creating pressure points when the subject increases the tightening force to close the gap.

In addition, by measuring general facial features of a subject and producing a sealing structure that conforms to the general characteristics, it is possible to achieve a microscopic custom production of a face sealing structure for a respiratory mask. However, the macro custom order process has the same disadvantages as the micro custom order process. That is, mass production of this type of, especially tailor-made, macro-custom-made masks is time consuming, uneconomical and inefficient.

Also, macro order-building cannot minimize the disadvantages of leakage resulting from the physical characteristics of the subject's soft tissue. For example, when there are deep wrinkles in the soft tissue, a macroscopic custom-built seal generally does not reduce as much wrinkling as a microscopic custom-made seal. Instead, the user has the problem of creating localized high pressure on the subject's surface, as the user typically increases the tightening force to minimize leakage.

Accordingly, it is an object of the present invention to provide a custom-made sealing structure that is in close contact with the surface of a user, and to form a sealed interface therewith, thereby overcoming the drawbacks of the conventional sealing structure technology. In one embodiment according to the present invention, there is provided a sealing structure having a first portion formed by a gel material and a second portion connected to the first portion,
The object can be achieved by including a selectively formable material, being shaped from a first pattern to a second pattern, and retaining the second pattern in response to the shaping.

The inventor according to the present invention provides, for example, that the first part forming the sealing structure of the respiratory face mask is made of a material such as a gel substance having spring properties similar to human fat,
The tension on the head straps used in cushion type respirators and the resulting compression of the mask on the user's face is substantially reduced. The first part of the seal acts like many natural biological tissues and tends to naturally fit the detailed contours of the user's face under the influence of small head strapping forces . Thus, the first part of the sealing arrangement has the effect of a microscopic customization, the sealing arrangement adapted to the detailed characteristics of the user's skin.

In addition to the above effects, the present inventor has discovered that a gel substance can be produced which resembles the spring properties of human adipose tissue. In one embodiment, the gel material is, for example, a viscoelastic polyurethane having a spring (rebound) property in which the sealing structure returns substantially to its initial shape after pressurization and an elastic property comparable to that of human adipose tissue. It is a polymer. In a further embodiment, the protective cover covers the outer surface of the gel material. In the absence of this type of cover, the inherent adhesive properties of the gel material help to increase the fit of the face sealing structure to the user's skin. On the other hand, when tackiness is not desired, the surface of the annular member (protective cover) is coated with a coating of powdered talc, silicone or a similar biocompatible material. However, it is preferred to encapsulate the exposed portion of the gel material with a thin, flexible membrane cover to increase the durability and wash resistance of the face sealing structure.

When the user wears an external device, such as a mask, having this type of sealing structure, the portion of the face sealing structure that comes into contact with the user simulates the recoil characteristics of human fat tissue. You feel natural substances on your skin. The respiratory mask having this type of sealing structure is custom made, since the sealing structure comprises a second part which is molded from the first pattern into a second pattern and retains the second pattern accordingly. , Matching the general facial features of the user. The second part of the seal creates the effect of a micro-custom order, the seal being adapted to the general facial features of the user. Therefore,
External devices, such as masks, provided by this type of sealing structure that can be made to order,
The mask is comfortably pressed against the user's face with less head strap tension than the known masks of the prior art, maintaining a sealed connection. In addition, due to the fatty nature of the gel material in the first part of the sealing structure, the gel effectively fills gaps in the user's surface and shapes the other contours of the face. This minimizes leakage of the pressurized gas supplied to the mask. In addition, the gel substance suppresses the growth of bacteria due to the foam-type mask sealing structure, and dissipates heat efficiently.

For example, it is preferable to provide a tab 25 or the like. The three holding devices of this type, shown in FIGS. 1 to 4, are arranged approximately at the corners of the mask 10, but without any other structure, arrangement, number and position of clamping devices without departing from the principle of the invention.

In the illustrated embodiment, the seal 18 comprises a solid, but generally annular, elastic member 27 having high resilience and self-sustaining compressibility, the elastic member 27 being a mask to which the elastic member 27 is attached. It has a peripheral wall 28 having a generally annular base or inner end 30 formed to substantially match the surface 16 of the body 12. Further, the peripheral wall portion 28 has an outer end portion 32 on a side opposite to the inner end 30. Outer end 32 forms a sealing surface 34 having an annular profile that closely fits against the user's face. As will be described more fully hereinafter, in the illustrated embodiment, the contour of the sealing surface 34 is strictly the structure of the user's face, especially the bridge of the nose.
It approximates the surface shape of the cheek adjacent to the nose, the gap between the nose and the upper lip, and the area adjacent to these. A wide variety of contours of the sealing surface 34 are provided, and the user selects a sealing material whose shape most accurately matches the facial shape, so that the sealing material and mask of the present invention are:

It will be appreciated that depending on the type of mask to which the seal is attached, the contour of the sealing surface 34 will have an alternative configuration. For example, full face mask (full face mask) (not shown)
In this, the sealing surface 34 has a contour that fits the lower jaw of the user instead of the area between the nose and the upper lip. In any case, changes in the structure of the user's face, especially in the bridge of the nose, require, for example, the adaptability of the seal to match multiple possible face profiles. Although various different profiles of the sealing surface 34 can be formed, providing a limited number of different profiles of the sealing surface 34 merely facilitates effective mass production of the seal 18 from a practical standpoint.

In the embodiment according to the invention shown in FIGS. 3 and 4, the entire annular elastic member 27 is made of a gel, for example a viscoelastic polyurethane polymer, having a resiliency or a spring characteristic approximately equal to that of human fat tissue.

More specifically, the sealant 18 is preferably measured with a durometer on a Shore 00 scale used for the elasticity of very soft elastic materials, and has an elasticity of about 10 or more, most preferably about 0.
It is. This type of resilience reads a durometer of 0 on the Shore 00 scale and is substantially consistent with human adipose tissue.

Adipose tissue, which is essentially capable of filling voids, has negligible structural integrity and is not self-retaining. Thus, a sealant having essentially the same structural properties as fat is impractical from a use point of view. That is, when the sealing material is formed of a material that cannot be structurally distinguished from human fat tissue with respect to elasticity, it tends to have an amorphous shape under the influence of gravity, and even if the tension of the head strap is very high, It will not match very effectively to the contours of the user's face. For this reason, properly designed seals, while not identical, must structurally, in particular, their overall elasticity, substantially resemble human fat tissue. The sealant exhibits a measurable springy "memory" that is structurally self-sustaining, and even with a small head tension of the string, the sealant gently abuts the user's facial microstructure,
When the contact with the face is released, the self-healing state is restored to the initial form by the resistance against the gravitational effect. In addition, the sealant must withstand deformation due to the positive pressure of the gas supplied to the mask.

To simultaneously achieve the above and other beneficial properties, it is preferred that the annular elastic member 27 of the present invention be formed from a gel material whose Shore 00 scale is substantially indistinguishable from human adipose tissue, using a durometer. Approximately 20-45 Shore 000 scale (this scale is used to measure the elasticity of very soft elastic materials) or represents elasticity. By comparison, human adipose tissue exhibits a durometer of about 10 Shore 000 scale.

The selectively formable material of the second portion 52 of the seal 218 is arranged in a conformable manner and is molded from a first pattern to a second pattern. Further, the formable substance is in a solidified state, and retains the second pattern after molding. In FIG. 6, the first pattern before molding in which the second portion 52 matches the contour of the subject, that is, the boundary surface 54 between the first portion 50 and the second portion 52 is indicated by a dotted line. On the other hand, the dotted line 56 indicates that the second portion 52 is the second
And a boundary surface between the first portion 50 and the second portion 52, which is formed in the pattern of FIG. In the embodiment of FIG. 6, the second portion 52, when molded into a second pattern, has a first portion 50 and a second portion 50 above and below the seal as a result of the molding.
The distance between the inner edge 30 and the boundary surfaces 54,56 between 52 and the inner edge 30 is reduced. This occurs, for example, because the bridge of the nose and jaws are protruding.

Embodiments of the present invention provide a customizable seal that matches an external device to the part of the subject, for example, around the subject's nose or around the nose and mouth, such as the mask shown in FIG. Provide materials. That is, by providing a material that can be formed as the second portion 52 of the sealant 218, the sealant can be macro-customized to provide a general exterior shape of the subject, such as the face of the subject wearing a mask. Align with the underlying bone structure of the part. In addition, since the gel has the beneficial effect of micro-customization to easily adapt to the features of the subject's facial contours, there is no need to form the gel to match the user's particular features, as shown in FIG. The first portion 50 of the gel material sealant 218 shown in FIG.
Does not suffer the disadvantage of micro-order production. Alternatively, when the seal is abutted against the user, the first portion fills the gaps on the user's surface due to the consistency of the gel. In this manner, a single seal 218 has the advantages of micro-to-order and macro-to-order manufacturing.

Further, the formable material of the second portion 52 can be reformed, if necessary, simply by changing the formable material back to a conformable state. In the above embodiment, this is performed by reheating the second portion. Thus, for example, if the customization prior to the sealant is insufficient for the subject, the sealant 218 may be reordered. Still further, without performing the time-consuming and generally permanent micro-customization process, the gel material of the first portion 50 produces a micro-customization effect and the second portion is custom-made. hand,
A commonly formed seal, having a first portion 50 and a second portion 52, matched to the general exterior shape of the subject, accommodates a wide variety of subject applications and maximizes the efficiency of the manufacturing process I do. This feature minimizes the variety of sealant stocks of various different shapes and sizes that must be utilized from a group of subjects with widely differing physical characteristics to provide a suitable sealant for each subject.

The method of customizing the sealant 218 to substantially match the characteristics of the subject's face first selects a sealant that matches the user. For example, the size of the seal 218 must typically match the size range of the user to be covered by the seal. For example, this can be accomplished by forming various sized seals 218 available to the user. After selecting an appropriate size seal, the formable portion of the seal 218 is changed to a conformable state. In a preferred embodiment of the present invention, at least the second portion 52 of the seal 218 is heated to a sufficient temperature to activate the thermally active material (curing agent) and change to a conformable state.

The step of heating the second portion of the seal can be performed in various ways. In a preferred embodiment of the present invention, the sealant 218 is immersed in a heated liquid, such as boiling water, for a sufficient time to cause the second portion 52 to change to a conformed state. Usually, 4 minutes or more is sufficient. Also, the second portion can be heated using, for example, an oven, a microwave oven, or by applying a heat source to the sealant.

After the seal has been heated to a sufficient degree such that the formable portion changes to a conformable state, the exposed portion of the seal 218, preferably the subject contact portion 32, is cooled to a substantial amount of non-human tissue. The seal can be applied to a person without pleasure or damage. For example, the sealing material is removed from the heated liquid and cooled in the air or in a cooling room such as a refrigerator to perform cooling. However, in a preferred embodiment, the seal is quenched with a liquid, e.g., water, at a temperature below the temperature at which the seal changes to a conforming state for a short period of time, typically less than the time it is placed in boiling water. Cooling takes place.

The relatively high thermal resistance of the seal prevents brief external cooling, eg quenching, from significantly affecting the flexibility of the second part. That is, the degree of cooling in the cooling process does not need to be changed sufficiently in the formable portion of the sealant, or starts to change to a solidified state due to the internal performance of the sealant for retaining heat and a relatively short quenching time. Temperature. The quenching is performed on all of the seals or is preferably restricted to the end surface 32 that contacts the user. The quenching time varies from subject to subject depending on the subject's thermal sensitivity. Since each part of the body has a part with high heat sensitivity and a part with low heat sensitivity, the quenching time is changed depending on the position of the body in contact with the sealant.

When the temperature outside the seal decreases to a temperature that the user can withstand, the seal is brought into contact with the surface of the user or the surface of the user is brought into contact with the seal. The user holds the sealant by hand or, if the sealant is a mask portion, tightens the mask against the user to abut the sealant. Preferably, sufficient force is applied to the seal to deform the second portion 52 into a shape that substantially matches the contour of the subject under the seal. The abutment of the seal against the user and the cooling of the second portion of the seal change the second portion from the conformed state to the solidified state, thereby resulting in the outer contour of the user beneath the seal. Is maintained in a shape substantially matching the FIG. 6 shows an example of the shape 56 of the second portion 52 by the above-mentioned custom production method by a dotted line. In this manner, the formable second portion of the seal allows for macro customization so that the seal is more accurately matched to the user's general outer shape and the pressure points are reduced. In addition, the comfort of the external device to which the sealing material is fixed can be improved.

FIG. 6 shows a substantially flat interface between the first portion 50 and the second portion 52, but the interface between the first portion 50 and the second portion 52 is flat It doesn't need to be.
In contrast, the sealing material allows the interface between the first portion 50 and the second portion 52 to be changed in three dimensions according to the required structural features. For example, FIG. 7 shows a seal 220 in which the interface 62 between the first portion 50a and the second portion 52a is generally flat over an area 64. However, the distance of the inner end 30 from the interface 62 decreases in the range 58, and much of the first portion 50a, which contains only gel material, is formed near the bridge of the nose.

The sealant in which the mixing ratio of the gel to the hardener gradually changes from the inner end 30 to the outer end 32 can be formed, for example, by combining the gel material with a specific mixing ratio and the hardener. It is formed by completely filling the casting with the substance. Place the casting in the centrifuge and the heavier hardener is pulled in the direction of the inner end 30 to disperse the layer or more precisely from the inner end 30 to the outer end
A structure in which the mixing ratio of 32 changes is formed. Based on the time course and / or speed of the centrifuge, the change of the mixing ratio from the inner end 30 to the outer end 32 is controlled.

In the present invention, the mixing ratio changes in three dimensions. For example, the mixing ratio of gel to hardener may decrease as one approaches inner surface 68 from outer surface 70, or vice versa. Also, the rate of change of the mixing ratio from one part of the sealant 218 to the other part need not be constant, i.e., linear. Rather, the rate of change of the mixing ratio may vary according to the desired characteristics of the sealant 218. Further, the physical arrangement of the range in which the mixing ratio of the sealing material changes can be changed according to the demand of the user.

For example, a second portion 50 of the sealant corresponding to the bridge of the nose identified as area 58 in FIG.
a is that the mixing ratio of gel to hardener is mixed 2: 1 throughout the second part, and then abruptly changes to the first part with only gel material. However, at the other portion of the sealant, e.g., portion 72 extending between each side of the nose and mouth, the mixing ratio of the second portion is about 40% gel material and 60% cure at the inner end 30. From the agent, the first part
At the junction of 50a and second portion 52a, it can range up to about 60% gel material and 40% hardener. From the first portion 50a, i.e., the interface 62, through the outer edge 32, the sealant composition is substantially 100% gel material everywhere. In short, in the present invention, the mixing ratio, the rate of change of the mixing ratio, and the arrangement of the mixing ratio are three times throughout the sealant as long as the sealant produces the above-mentioned micro-order production and macro-order production.
It can be changed by dimension.
